The Long Tail of Life

Saved for future reference from kottke.org:

the Long Tail of Life: During an 11 month study in 2007, scientists sequenced the genes of more than 180,000 specimens from the Western English Channel. Although this level of sampling "far from exhausted the total diversity present," they wrote, one in every 25 readings yielded a new genus of bacteria (7,000 genera in all).

Man, guys, sequencing is the coolest.
